In 2013, at the suggestion of oceanographer Charles Moore, geologist Patricia Corcoran and artist Kelly Jazvac travelled to Kamilo Beach, Hawaii to study a new type of stone they have described as 'Plastiglomerate.' It consists of a mix of molten plastic debris and beach sediment, including sand, wood, and rock. Also of note is the origin of the plastic debris on Kamilo Beach: it mostly appears to be foreign to Hawaii.

A co-authored manuscript of their findings, and related press, can be found here:
